Go to Best Buy this Friday or Saturday and you may be able to get a free Guitar Hero II game and guitar with the purchase of an Xbox 360 (total price of $349.99). This is a "doorbuster" deal and not advertised in the Thanksgiving day ad. It is in store only.

I say "may be able to get..." because there are limited quantities and you'll need a "ticket". I assume this means that you'll need to be in line early.

Other Xbox 360 doorbuster deals include $20 off Stuntman Ignition, $10 off Call of Duty 3: Gold Edition, $10 off Ghost Recon: Advanced Warfighter 2, and $10 off Spider-Man 3.
